Fig. 5 is an elevational view of a pump plunger of the dispenser as when removed from the remainder of said dispenser; and

Fig. 6 is an elevational view, partially in section and partially broken away, of a hollow slide valve or sleeve of the dispenser as when removed from the remainder of said dispenser.

A stationary hollow casing or cap member of the new and improved dispenser is denoted I0. While said stationary hollow casing or cap member Iil could be otherwise constructed, it is in the disclosure as made of. an integral mass of plastic material.

A body portion II of the hollow casing or cap member I0 is of general cylindrical configuration and includes an annular flange or skirt portion I2 at its periphery having an internal thread I3 adapted to be turned down upon an external thread I4 on the mouth or neck of a bottle or other container, such, for example, as the bottle indicated I5.

An extension portion I6 of saidhollow casing or cap member I0 also is of general cylindrical configuration as disclosed. More explicitly, said extension portion IB is constituted as an elon gated member which is integral with and extends outwardly or downwardly from a central part of the body portion II in spaced, substantially concentric relation to the annular flange or skirt portion I2. Desirably, the construction and arrangement will be such that whenthe dispenser is applied to a bottle or other container the outer or lower end of the extension portion I6 of said dispenser will be situated in proximate or adjacent relation to the bottom wall of said bottle or container and theexterior side surface or surfaces of said extension portion IE will be situated in spaced relation to the side wall or walls of the bottle or container, about as disclosed in Fig. l of the drawing.

An elongated pump chamber I! of the stationary hollowcasing or cap member ID, cylindrical as disclosed, is defined at its outer or lower end by a transverse closure well I8 at the end of the extension portion I6 spaced from the body portion II and at its circumference by an internal cylindrical wall I9 of said extension portion. A concavity 20, of cylindrical configuration as disclosed, in the outer or upper surface of the body portion I I is in surrounding relation'to the inner or upper end of the elongated pump chamber IT, and said elongated pump chamber is continuous from the location of said concavity 2D to said transverse closure wall I8. A base wall 2I of the body portion I I, defining the base of the concavity 20, is in surrounding relation to the inner or upper endof the pump chamber I! and as shown is in perpendicular relation to the longitudinal axis of the extension portion I6. An outer or lower inlet port 22 in an outer or lower part of the cylindrical wall of said extension portion I6, adjacent the transverse closure wall As disclosed, the inlet and outlet ports 22 and 2'4 are at diametrically opposite sides of the pump chamber ll although this seem nnecessarily be the relative arrangement oi saidportsl A hollow slide valve or sleeve 25 of the dispenser, of cylindrical configuration--'as 'show-n;

mounted within the pump chamber for free reciprocatory movement longitudinally of said pump chamber, and a pump plunger 26-; also" of cylindrical configuration in the disclosure as made, :is mountedwithin the? hollow slide valve or sleeve 25 in such; manner that atsome times duringoperation ofthe; dispenser said pump plunger 26 will be given longitudinal movement in the pump chamber as a unit with saidhollow slide valve or sleeve and at othertimes during operationxof saiddispenser the pump plunger will b'e given longitudinal movement in said pump chamber-relative tothe hollow slide valve or sleeve. Stated otherwise; said; pump plunger 26 is snugly mounted in the hollow slide valve or eeve 25 to be frictionally sl-idable in said hollow slide valve or sleeve and the hollow slide valve or sleeve is snugly mounted withinhtheqpump chamber H; to be freely slidable in said; pump chamber. An operating pieceor head upon the pump plunger: 28,- lsituatedat'the outer or upper sideof the body portion l l at the location of the concavity 2|],is-indicated 2 1, and-a coil spring 23, insurrounding relation to said pump, plunger 26' betweennan, inner surface; ofthe operating piece or head .2'land the base wall 2 l of said concavity 20, is adapted normally to urge the pump plunger outwardly or upwardly of the pump chamber [7.

An elongated slot? in an upper portion of; the hollow slide valve' or sleeve "25 is, denoted 29; an outlet port in a lower portion ofivsaid hollow slide'valve or .sleeveis represented "30;, and an elongated slot in an upper-portion of the pump plunger 2-8"- isdesignated" 31-. A' stoppiece or peg has its exterior; end portion'fixedly, located in an upper portion of the wall of thewflexte'nsion portion it and its interior end portion situated within the elongated slots 29 and 3! in said hollow slide valve or sleeve 25 and said pump plunger 26; respectively.

Theconstruction and arrangement will be such that outward or upward movement of the'pump plunger 26 will be arrested by engagement of an inner or lower limiting surface 33 of said pump plunger, defining the inner or lower end of the elongated slot 3i, with the stop piece or peg 32 and that inward or downward movement of the pump plunger will be arrested by engagement of an outer or upper limiting surface 36 of said pump plunger, defining the outer or upper end of said elongated slot 3!, with'said stop piece or peg 32. The construction and arrangement also will be such that outward or upward movement of the hollow slide valve or sleeve 25' will be arrested by engagement of aninner or lower limitingsurface 35 of said hollow slide valve or sleeve, definin the inner or lower end ofthe elongated slot 29, with the stop piece or peg 3-2 and that inward or downward movement of the hollow slide valve 01' sleeve will be arrested by engagement of the outer or lower end of said hollow slide valve or sleeve with the transverse closure wall l8. The outer or lower end or edge 36 of the hollow slide valve or sleeve 25 is in perpendicular relation to the" longitudinal axis of said hollow slide valve or sleeve and in parallel relation to the internal sii'rface of said transverse closure wall l8, andwhen the outer or lower end or edge of the hollow slide valve or sleeve is seated against said internal surface of the transverse closure wall I8,- an' interior space within said hollow slide valve dr'sl'ee've' adjacent the outer end of or below the pump plunger" 26will be sealed off from the inlet port 22; Also, when the hollow slide valve or sleeve 25 is situated so that its outer or lower end sa'ted'against the interior surface of the transverse closure wall IS, the outlet port 39 of said hollow slide valve or sleeve will be alined with-the outlet 13911124 in the extension; portion l 5 in= cqmmunicatingrelatioii with" the discharge outlet 23. Itj is the remiss or the stop piece or peg 3 2 additionally to preclude ro'tat'ive movement ofthe hollow slide va ve or sle 62511 1 the elongated pump chamber 11w insure teat me outlet ports 39 and- 24 constantly will lie 'a; plane passed longitudinally through the" extension portion 16-. Stated otherwise, it isfiebes'sary that the outlet port 30 constancy be set remove to the outlet port M so that said ot er ports' wm be alined when the hello slide vaive of sleeve 25 is at its innermostpositi'onarid in' the disclosure as made t'he stop "iece or" peg; 22 constitutes means for real said Hollow slide valve or sleeve again my inent of'rdtation' thus to insure nmenem'ersndtanet porters and 36.

In Fig; 0f the drawing; the pl nger 25 and the hollow slide valve oi'sieeveis are di'sclds'ed as when retained at their outer f' mostpos itions by the @011 spring 28; the 1mm mg surface 33 of said' pump plung'rahd thelifiiiti'ng' surface 35; of said hollow siiaevaw'ofsiseveta ing engaged againstthstop piece or'jpegazi Assurning thatliduid bstance' in thebot'tle [5 also fills the lower portio'nsof the purrib fi rnber l1 and the hollow slidei 'valveoi sleeve 25 beneath the pump plunger 28 and sad plunger manually to'be depressed, a st;r s'ilie'fit' action of the coilspring- 28, the plunger" and said hollow slide valve or peeve 1111 any will ben'io'vd inwardly oi: downwardly of the bottle together as a unit until the'outer or lower end of the hollow slide valve or sleeve has engaged the interior surface of the transverse closure wall- 18. During this initial inward or downward movement of'said pump plunger and the hollow slide valve or sleeve; liquid substance willbe pushed backwardly' to an unimportant extentthrough the inlet port 22 into theinterior o-f-saidbottle.

In Figa- Z-the pum plungerand-the hollow slide valve or sleeve are disclosed situated as when said pump plunger manually has been pushed irrwardly to extent just sufli'cient to'ca-u'se the outer or lower end "or said hollow-slide'valve or'sleeve to be engaged against the interior surface of the transverse closure wall 18; the inlet port 22 tobe 'cl'osed' to passage ofliquid substance backwardly through said inlet port,.and the outlet ports 30 and 24 tube-alined: Of course, inward movesaid hollow slide valve or sleeve in response to inward movement of the hollow slide valve or sleeve, instead of by engagement of the outer or lower end of said hollow slide valve or sleeve with the transverse closure wall I8, as will be understood. Supposing the pump plunger and the hollow slide valve or sleeve to be situated as in said Fig. 2, or as when movement inwardly of the bottle of said hollow slide valve or sleeve has just been arrested by engagement of the outer or upper limiting surface of the elongated slot 29 with the stop piece or peg 32, and manual depression of said pump plunger to be continued, the pump plunger will be moved inwardly or downwardly of the bottle relative to the hollow slide valve or sleeve thus to cause liquid substance to be emitted from the discharge outlet 23 by way of said outlet ports 30 and 24.

In Fig. 3 the pump plunger and the hollow slide valve or sleeve are disclosed as when said pump plunger has been pushed inwardly of the bottle to its extreme extent so that the upper limiting surface 34 of the elongated slot 3| is engaged with the stop piece or peg 32 while said hollow slide valve or sleeve also is at its extreme inner position. Supposing the pump plunger when situated as in said Fig. 3 to be released, said pump plunger and the hollow slide valve or sleeve initially will be moved outwardly or upwardly of the bottle together as a unit, in response to resilient action of the compression coil spring 28, until the inner or lower limiting surface 35 of the elongated slot 29 of the hollow slide valve or sleeve has engaged the stop piece or peg 32. During this initial outward or upward movement of said pump plunger and said hollow slide valve or sleeve, liquid substance will be per mitted to enter the interior space within the hollow slide valve or sleeve adjacent the outer or lower end of said pump plunger by way of the inlet port 22, and at the same time the outlet port 30 will be moved out of alinement with the outlet port 24.

In Fig. 4 the pump plunger and the hollow slide valve or sleeve are disclosed situated as when said pump plunger has been moved outwardly by the compression coil spring 28 to extent just sufiicient to cause the inner or lower limiting surface 35 of said hollow slide valve to be engaged against the stop piece or peg 32. As shown in said Fig. 4, the inlet port 22 is open to the interior of the lower portion of the pump chamber I1 and the outlet port 30 is out of communication with the outlet port 24. Supposing the pump plunger and the hollow slide valve or sleeve to be situated as in Fig. 4 and outward movement of said pump plunger by the compression coil spring 28 to be continued until the parts are situated as disclosed in Fig. 1, the pump plunger will be moved outwardly or upwardly of the bottle relative to the hollow slide valve or sleeve thus to cause liquid substance to be drawn or sucked through the inlet port 22 into the outer or lower portions of the pump chamber I1 and the hollow slide valve or sleeve 25.

It will be obvious that the dispenser as illustrated and described can be manipulated to cause measured amounts of a liquid substance to be dispensed from a container such as the bottle l5. With each outward movement of the pump plunger 26, adapted to be accomplished by resilient action of the compression coil spring 28, a measured quantity of the liquid substance will be loaded into the dispensing device, and

with each inward movement of said pump plunger, adapted manually to be accomplished, a measured quantity of the liquid substance will be removed from said dispensing device. The discharging operations will occur with movement of the parts of the dispenser from their positions as in Fig. 1 through their positions as in Fig. 2 to their positions as in Fig. 3, and the re-loading operations will occur with movement of the parts of said dispenser from their positions as in said Fig. 3 through their positions as in Fig. 4 to their positions as in said Fig. 1.
